TIRE-BUILDING MACHINE.

Application filed (Jetober 16, 1920.

lie it known that l. llxio'ron Y. Loran, a subject ot the King ot' (treat Brit-ain. residing at llartt'ord. county ol llartl'ord. and State ot' Connecticut have invented certain new and uset'hl Improvements in Tire- Building l\f`lachines. ot' which the following is a tull. clear. and exact deseription,

Tires are manufactured in various ways. One method in extensive use is to build up an endless cylindrical hand ot superimposed layers ot fabric and rubber. which hand is subsequentl)Y roughly shaped to tol-n1 hy distension. intermediatelv while its edges are drawn together. In this method it is desirablel to build the cylindrical band or carcass on a collapsible. drum. The present invention relates to a machine 'for supporting and actuating such a drum.

Tire. building machines ot' the type mentioned have hereto'lore heen constructed with a main-shaft.7 which is adapted to carry the drum, supported in a frame. and driven by a Second and righi-angularl)v disposed shaft whieh is belted outside of the frame ot' the machine to a suitable source of power such as a counter shaft on the ceiling ot' a room or building. rlhe external shalting is in the 'ai'. unduly obstruets movement about the room. and is a danger- The present invention ainls to provide a unitary tire huilding machine that is complete within itselt` i. e., it earries or contains its own motor or source, ot power as well as driving eonneetions to the main-shaft or the building drum. The driving connections between the motor and drum are eompaotly arranged within the machine to economize floor spa-ee. The motor and mechanical elements are housed within the Yframe to protect them from dust as well as to allow free circulation of air about thel motor`r facilitating dissipation ol: heat during operation tl'ielreot'. Still further, it aims to diminish vibration by augmenting-the weight of the trame and constituent instrunfientalities with the weight of the driving motor. the building drum on the outside of the frame being balanced in part at least by the motor on Serial No. 417,411,

the inside ol the frame. Generally. the invention contemplates a more ettieient. reliable. and durable machine of the tire bnilding type.

The invention is illustrated in the accompanving drawings. in which- Figures l and Q are side and end elevations respectivelyv olt a machine embodying the principles ot'the invention. parts of the frame being broken awa;v to more fully clisclose the Construction.

iIn the maehine illustrated in the drawings. the iraniey l as shown is of a hollow box-like form with its top 2 closed or covered over by metal integral with its side walls. More or less rectangular openings El filled by suitable cover plates. one of which is indicated in the end walls at 4, are provided to cornpletel)v enclose and protect the parts within the trame from dust while allowing access thereto when necessary. main-shaft 5 and jack-shaft 6 are suitably supported in bearings in opposite side walls ot the 'frame in the npper and lower portions respeetiif'el';v thereof. the 75 main-shaft 5 having a free end 5 projecting outside of the traine and adapted to receive a eollai'isible drum (not shown) such as diselosed in a patent to Ernest Hopkinson. o. LSIOOL granted July 22, 1919. 80

The mainand jack-shafts 'and 6 are preferably arranged in parallelism and intermediate these shafts and preterahl)- with its axis in a vertical plane with their axes is arranged a motor indicated genezmll'v by g5 the numeral 7. The motor is hoff ,il within the 'Frame and at one side hinged as indicated at S. while on its other side its base is provided with an adjustable supporting screw 9 adapted to rest upon a lug l0 inte- 90 gral with or otherwise fixed to the opposite, side ot the frame ol' the machine. `Flexible connections such as chains l1 and l2 operatively connect the jack-shaft with the inotor and the main-shaft respeetivelv` the chain l2 being connected to a gear 13 on one end of the jack-shaft and the chainv ll being connected to a combined fly Whei and gear 14, The combined gear and fly wheel 14 is forn'ied integral with or otherwise loo suitably connected to the driving member A second foot treadle 23, on a shaft 24Cv having an arm 25 linkedlas indicated at 26 to a brake lever Q7 which carries a shoe Q8 adapted to engage a brake wheel Q9 fast on the. main shaft 5, is interoperatively connected to the first mentioned toot lever 22 by a slotted arm 3() and pin 31 connected to each of the levers as clearly shown in Fig. 1, ".Depression oi` the treadle 22 shifts the collar 18 and disengages the driving 1nem bers of the clutch, and at the saine time applies the brake, incidentally lifting the second treadle 23. 0n the other hand, depression of the treadle 23 throws the brake Ot and engages the clutch parts to start rotation of the mainshaft 5. Through the pin and slot connections :3U- 31, the treadles are thus rendered elective only in alternation.

Havino" thus described my invention, what l'etlaim and desire to protect by Letters Patent is :f

l. unitary tire building machine having in combination, a ,hollow trame adapted to rest on the door or' a building, a mainshatt rotatably supported in the upper portion of the frame and having a free projecting end adapted to carry a' drum on which tires may be built up, a motor housed within the frame, and driving connections between said motor and main-shaft including a inan- `ually operable clutch.

2. A. unitary tire building machine having in combination, a hollow l'rame with a closed top and a downwardly open supporting base, a mainshaft rotatably supported in the upper portion oi the trame and below its top, said main-shalt having a Jr'reo projeeting end adapted to carry a building drum, a motor housed within and. supported by the frame below said main-shaft, a jackshal't located below the motor, flexible drivl ing;l connections between the motor and jacksha't and between the jacltand [nainshalts, and means lor coupling and unconplingthe 1nain-shal`t l'ro'ni driving relation with the motor.

5. A unitary tire building machine having in combination, a hollow frame closed at the top, mainand jack-shafts operatively supported in the upper and lower portions of the frame, respectively, a motor supported by and within the outlines of the frame intermediate said shafts, a clutch on said ack shaft having' driving and driven members fixed and shit'table respectively to `and on said jack-shaft, a combined ily wheel and gear fixedly secured to said" driving member otfthe clutch, flexible connections between the combined fly wheel and gear and the motor and between the jacl and mainshafts, ay brake for retarding rotation ot' saidiinain-shaft, and interlocking treadles supported by the trarne for governing the operation oit the clutch and brake respectively, said treadles being operative only in alternation whereby when the clutch is uncouplod the brake is vapplied and when the brake is relei'ised the clutch is coupled.
